TensorFlow is an end-to-end open source platform for machine learning. In affected versions under certain conditions, Go code can trigger a segfault in string deallocation. For string tensors, `C.TF_TString_Dealloc` is called during garbage collection within a finalizer function. However, tensor structure isn't checked until encoding to avoid a performance penalty. The current method for dealloc assumes that encoding succeeded, but segfaults when a string tensor is garbage collected whose encoding failed (e.g., due to mismatched dimensions). To fix this, the call to set the finalizer function is deferred until `NewTensor` returns and, if encoding failed for a string tensor, deallocs are determined based on bytes written. We have patched the issue in GitHub commit 8721ba96e5760c229217b594f6d2ba332beedf22. The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, which is the other affected version.

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can trigger a denial of service via a segmentation fault in `tf.raw_ops.MaxPoolGrad` caused by missing validation. The [implementation](https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/core/kernels/maxpooling_op.cc) misses some validation for the `orig_input` and `orig_output` tensors. The fixes for CVE-2021-29579 were incomplete. We have patched the issue in GitHub commit 136b51f10903e044308cf77117c0ed9871350475. The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.

Libmenu-cache 1.0.2 insecurely uses /tmp for a socket file, allowing a local user to cause a denial of service (menu unavailability).

Insufficient input validation in the SNP_GUEST_REQUEST command may lead to a potential data abort error and a denial of service.

Improper input validation in the firmware for the Intel(R) Ethernet Network Controller E810 before version 1.6.0.6 may allow a privileged user to potentially enable a denial of service via local access.

Improper input validation in some Intel(R) Optane(TM) PMem versions before versions 1.2.0.5446 or 2.2.0.1547 may allow a privileged user to potentially enable denial of service via local access.

An improper input validation vulnerability in the UEM Core of BlackBerry UEM version(s) 12.13.0, 12.12.1a QF2 (and earlier), and 12.11.1 QF3 (and earlier) could allow an attacker to potentially cause a Denial of Service (DoS) of the UEM Core service.
